I've already answered in your soon-to-be diary. Didn't know where the application was. Since it is in the wrists and just 1.5 spray, still I'm doubtful about the none content of Wolf to cause this. Where were you when having headaches? Indoors/outdoors, what temperature, which activity (studying, socializing, working, online playing?) Also what time of the day, night, afternoon, morning? And the weather, too much sunny, too humid, cloudy or stormy? Did you sleep, eat or drink conveniently that day? Many other factors can give us headaches or rashes and pheromones are not to be blamed for.

Another reason can be that you're getting used to a new scent that you not wore before. Wolf has not an amazing sillage but persists for a long time. Which fragrances do you use to wear?
